"Polybius is an alleged 1981 arcade game described in a 1998 urban legend...
The urban legend is that the game was part of a gornment-run crowdsourced psychology experiment, with gameplay producing intense psychoactive and addictive effects in the player. These few publicly staged arcade machines were said to have been visited periodically by men in black for the purpose of data-mining the machines and analysing these effects."
So to recap, here are our parallels:
Polybius: described in a 90's urban legend to be capable of mind control.
Degenertron: described in a 90's conspiracy show to be capable of mind control.
Polybius: emptied periodically by strange men.
Degenertron: emptied periodically by a strange man.
Polybius: described to be mind-destroyingly addictive
Degenertron: described in the advertisements to be mind-destroyingly addictive
Ladies and gentlemen, I think we have a mind-controlling video game on our hands in VC.
